联盟是主权国家之间为了安全合作而针对成员之外国家签订的正式和非正式的协议关系。由于不对称联盟结构的特性使然，实力地位相差较大的小国通常面临更多的联盟困境。在联盟不同阶段，小国分别面临自主与安全威胁、连累与抛弃的局限性以及联盟的动态变数困境。冷战以来，韩美同盟对韩国外交的影响主要体现为：依附于美国的追随外交；自主外交历尽艰辛难以实施；平衡外交困难重重。尤其是美国的亚太“再平衡”战略，进一步加剧了韩国对外政策的“两难选择”。因此，韩关不对称同盟是韩国外交困境产生的根源和实质所在。

Alliance is defined as the security cooperation between member states with formal and informal agreements, in order to keep their security against non-member states. Due to the asymmetric structure of the alliance, small countries usually face more alliance dilemma compared to big countries. In the different stage of alliance, small country will face different dilemma, from independent interests and security threat, implicated and abandoned to dynamic dilemma. The asymmetry between the ROK-US alliance relationships has a profound impact on South Korea＇s diplomacy after cold war： its foreign policy completely attached to the United States, difficult to implement independent foreign policy, hard to implement a balanced foreign policy. U. S. ＇s strategic rebalance to Asia had further exacerbated the ＂dilemma＂ of ROK＇s diplomacy. Therefore, ROK-US asymmetric alliance is the source and essence of ROK＇s diplomatic dilemma.
